HEATING AND VENTILATING BUILDINGS.

SPECIFICATION forming part of Letters Patent No. 362,116, dated May3,1887.

Application filed August 14, 1886. Serial No. 210,944. (No model.)

To aZZ whom it may concern:

Be it known that I, Mronnnr. RUMBAUGH, of Cincinnati,county ofHamilton,and State of Ohio, have madea new and useful invention inHeating and Ventilating Buildings, of which the following is aspecification.

The object of my invention is to provide a convenient and economicalmeans of heating and ventilating buildings. For this purpose I constructthe building with vertical fines extending in the space between thewalls and communicating at their upper and lower ends with the externalair. These fines I divide by a transverse partition or cut-off plate ator near the floor-level of the room with which it is designed tocommunicate. I also construct horizontal fines between the joists of thefloor, one for each of the said vertical fines and communicating withits corresponding vertical flue below the transverse partition thereof.These horizontal fines I provide with an orifice opening into anairtrunlqwhich passes around or in close contact with the heater withinthe room to be heated and ventilated and opens at or near its top intosaid room. I further form an aperture through the wall of the room intothe upper division of the vertical fine, in which upper division. Iplace the smoke-stack or escape-flue for the products of combustion,introducing these products of combustioninto it through a suitable pipe.Either or all of the fines, or the apertures communicating with them,may be provided with any convenient register or valve for regulating thedraft. My plan contemplates avertical fine and a correspondinghorizontal fiue for each room to be ventilated. These fines occupy nospace otherwise available,and,being completelyhidden,do not disfigurethe building, either externally or internally, while they add little tothe expense of construction. They afford aeompletely independent meansof ventilation for each room. The fresh air, being brought first intocontact with the heater,distributes its heat throughout the room, andpure air is thus obtained at the desired temperature and without theinconvenience of cold drafts.

In the drawings, Figure 1 is a face view of portion of the inner wall ofa building having the lathing and plastering removed in places Fig. 6 isa modification of Fig. 2, having also a portion of the j acket of theheater broken away. Fig. 7 V is a horizontal cross-section taken throughz a, Fig. 5, showing, however, the smoke-pipe in perspective.

A A represent vertical fines between the walls of the building B 0,having partitions a.

D D represent horizontal fiues communicating with the vertical fines,respectively, and opening at 1) into a trunk or drum or jacket,-i',inclosing the wall of the heater G, or a portion thereof. This drum isopened at the top, so as to allow the air, after passing in contact withthe heater,to escape into the room. If desired, a register may beprovided at this point to regulate the current of infiowing air.

H H represent the several fioorsof the building; at d, thejoists of thefloor; K, the apertures from the room into the upper division of thevertical fines; E the smoke-stack, entered by the smoke-pipe F throughsuitable orifice, f. By providing an orifice, Z, to the smoke-stackopposite the aperture K, and a removable cap for such orifice, I am ableto readily remove the soot from the smoke-stack. The external airreaches the lower end of the vertical fine through apertures M, whichmay extend in either direction, and either communicate with a commoninlet-pipe or directly with the outside of the building. The upper endof the flue may communicate with the outer air through the chimney, orin any other convenient place.

In the modified form of construction shown in Figs. 5, 6, and 7 Idispense with the interior smoke-stack and separate the smoke-fine Nfrom the airfiue by any suitable partition, g. The heat from the heatercauses the air in the drum to ascend,thus creating a suction to draw inthe external air whenever the room is to be warmed for use. At the sametime the smoke flue serves to heat the air in the vertical air-flueabove the aperture K, causing it to rise and I creating a suction todraw off the impure air from the room. The course of the air from theflue is represented by arrows.

It will be seen that I have thus an indepen dent and economical means ofventilation for each room without occupying space that might otherwisebe available for other purposcs,while the heater, without the additionof other mechanical means of any kind, furnishes the necessarypropulsion to both drawin the fresh air and exhaust the impure air.

While I have shown a jacket or drum as a convenient method of bringingthe cold air in contact with the stove before its discharge into theroom, I do not mean to confine my invention to the particularconstruction of this passage or chamber. The inflowing air may becarried by a pipe through the stove or other heater, or brought intocontact with it in any other suitable manner so as to be heated beforebeing discharged into the room.

Various forms of heater may be used. If a steam-heater is employed, thesteam-pipe may be carried from story to story. through the escapeair-flue, or in such proximity with it as to afford the desiredpropulsion for the air in the flue, in lieu of the smoke-stack orparallelfiue.

The fines for ventilating the second floor have the transversepartitions or cut-off plates located therein at or near the level ofthis floor. The same is true of each successive floor, the arrangementbeing the same in respect to each fioor,asshown and described moreparticularly with reference to the ground fioor. These flues can bevaried in shape and arrangement,

according to convenience or to suit the taste of the architect..

I claim- 1. In combination with the wall of a room, a flue having atransverse partition near the floor-level, a communication with theouter air below the partition, and another communication with the outerair at its upper end, a flue extending between the joists of the floorfrom the lower division of the first-mentioned flue and communicatingwith a pipe, whereby the inflowing air is brought in contact with theheater and thence discharged into the room, an aperture from the roominto the up per division of the first-mentioned flue, and the pipethrough which the products of combustion are carried off from saidheater, extending,in contact with said flue,between said aperture andthe discharge-opening, substantially as herein described.

2. The herein-described means of ventilating a building, consisting of avertical fine for each room, extending between the walls, havingcommunication with the external air at their upper and lower ends, andhaving a transverse partition near the floorlevel of the room with whicheach communicates, horizontal fines extending between the floor-joists,each communicating with its respective vertical flue below its partitionand with the surface of the heater of the room, and thence with the roomitself, and an aperture leading from said room into the foul-air flueabove the transverse division-plate, substantially as herein set forth.
